Adjoining the districts of Paro, Chhukha and Samtse, Haa valley is one of the most picturesque places in the Kingdom, spread over an area of 1706 sq. km. During pre-Buddhist era, Haa valley was known for its animist tradition. Inhabitants then were enthused in offering animal blood to their local deities. Such animist belief however was transformed into peaceful Buddhist tradition in 8th century by Guru Padmasambhava. The tantric master, Guru Padmasambhava, subdued the local deities like Ap Chundu and made the guardians of the Buddhist tradition. However, the traces of this belief system are still noticed in the form of festivals and rituals.
